That's a pretty good bus speed for a KT133 board. My board topped out at 112Mhz, but could run it 100% stable there all day (well actually for several years) with the memory at 149Mhz max timings. I am still running my Duron 600 at 900Mhz after all this time on my Abit KT7.

Did you unlock that thing or are the multipliers remapped on it for the higher ones? As far as I knew those older board never supported past 12.5x.

Welcome to the "KT7's That Just Won't Die Club". Look's like you picked up a good CPU to boot, nice O/C. I think I will bite the bullet soon and go to N-Force2 system, going to miss this board, it's been the most stable board I've ever owned.

i had to unlock the upper multipliers. i took a very small strand from a braided wire and jumpered between socket holes AJ27 and one of the Vcc's in row 26. no soldering, no cutting traces, no special conductive liquid, no precision tools. oddly enough, the default boot was 5x, and it remapped to 20x. the same trick will work for unlocking lower multipliers for the faster Tb-B's, just take AJ27 to a ground in row 28 instead

112 seemed to be the topline FSB for most people, a couple got to 118/38. i should probably mention i had replaced the stock hs/f from the northbridge with a similar-sized bare heatsink from an old video card. it had fins that were twice as long to make up for the lack of fan. the fan had crapped out about 2 years ago.

i can get another 3C cooler with my original Alpha PAL6035, but the damn thing is too loud, ~40dB vs the 26.5dB Speeze.

Yah. Lots of people had trouble with the fans on those KT7 boards. My fan needed to be cleaned and oiled about every 3-6 months (depending on use). It seemed to run stable thought with the fan dead (at least for a few weeks every now and then). One thing I really liked about that board is that it supported very low voltages. At the stock 600Mhz my Duron ran at like 1.35v (instead of the higher 1.6v). I had the thing at 950Mhz, but I just didn't see the point. I ran it at 935Mhz for a few months, but ended up running it at 8x112. My unlocking did not last that well and the .5 multipliers stop working most of the time when I booted up so I could not use 8.5 reliably. Still running a stock GlobalWin FOP32-1 on the thing, but the fan clips rattle a bit. The kids mostly use that computer anyways.

The fan on my KT7A chipset went dead some time ago, didn't have a spare one so I'm running the chipset heatsink without a fan on it. I have severe case cooling though. dual 120CFM 120mm intakes connected to rheobus and 2x high performance exhaust fans connected to rheobus. Case temp is 30C when all fans are at 7V and 23C when all fans are at 12V. (CPU fan is always at 12V)

i really dont think heat is too big an issue on the kt133. even with just a little heatsink, it doesnt even get warm to the touch. the abit was meant as an OC board and the fan was either a marketing move or overestimate of heat dissipation

I guess the KT133 is still a nice chipset to have, even if it only supports PC100/PC133 SDRAM

The fan on my KX7 started grinding the other day and this board is only a couple of months old. So, I took that tiny little heatsink off, and put AS3 on the Northbridge and it has been running fine, without a fan for days!
